What is the cause of pre-cancerous cells in the uterus?

The cause is because of carcinogen factors like HPV virus(which can be contacted by exterior) or other substances like nitrites which alterate the DNA of the cells. A healthy way of life can avoid this.

Pre-cancerous cells in the uterus are caused the same way any other pre-cancerous cell is formed. This may be a result of a virus, environmental exposure, infection, or other process. Doctors aren't really sure what causes cancer. The important thing is to have it treated the way your doctor recommends so that you don't have further problems.

Pre-cancerous cells originate in the cervix, and are called cervical dysplasia. Cervical dysplasia may progress to cervical cancer, and progress to the uterus. The human papilloma virus, other strains of genital warts and smoking may contribute to pre-cancerous cells. Pre-cancerous cells are almost always completely treatable before they progress to cervical cancer.

One main cause is an HPV infection. Sometimes pre-cancer cells from the cervix show up in the uterus. There is no definite known cause. Sometimes the normal cells just go crazy and start to multiply wrongly. If caught in time this condition is usually very treatable and sometimes a hysterectomy is needed.

The main cause is HPV (Human Papiloma virus). Other causes are sexual promiscuity, inmunodepression, contraceptive hormonal treatment, starting sexual life at a early age, fat based diet, even tabaquism.
